变异语音识别技术是飞机座舱中语音识别系统必需解决的关建技术之一。一些成熟的民用语音识别技术难以解决此问题，因此，需找出适于变异语音的特征参数，用谱斜率决定的加权法作变异语音特征，又是本文在这方面的有益学试。
Variation speech recognition technology is one of the key technologies that must be solved in the speech recognition system of aircraft cockpit. Some mature civil speech recognition technology can not solve this problem. Therefore, it is necessary to find out the characteristic parameters suitable for variant speech and use the weighting law determined by spectrum slope as the variation speech feature. This is also a beneficial experiment in this dissertation.
